Introduction Taping drywall is almost an art form. It takes practice and a lot of patience. A good taper can hide any mistakes that were made in hanging the drywall. To finish drywall, you must tack corner bead to all corners. Then, apply joint compound to all seams, nail and screw holes and corners. When joint compound dries – it shrinks. Therefore, 3 coats of compound will be needed with sanding in between coats.

Helpful TipsSanding drywall compound is a messy, dusty job. Close doors or hang thin plastic sheeting in doorways to prevent dust from drifting to other parts of your house.

Drywall compound can dry out and/or separate in its container during storage. You may need to mix it up a bit and possibly add a little water. You want a smooth and moist consistency, but not too wet.

Instead of dispensing the compound directly from the pail, use a plastic trough, which will allow you to move around faster and easier.

Don’t over-apply drywall compound. It is more effective to apply several thinner coats. Also, thinner coats will dry faster.

1.

For corners

Using tin snips, cut corner bead and tack in place with nails spaced about 5” apart through the holes manufactured into the bead. The bead is designed to protect the outside corners of your room from dents.

2.

On the outside corners, apply compound from the trough with passes toward the bead. Scrape off the excess in a downward stroke with the edge of the blade extending beyond the corner.

3.

At the end of walls, apply compound in-between the two corner beads. Slide your knife down the beads to smooth.

4.

Inside corners

Apply a thin coat of compound to the corner area wide enough to extend past the width of the tape. Using your knife, embed paper tape in compound.

5.

Next, cover with compound on one side, and when it has dried, coat the other side. Use a corner knife to apply second and third coats with a light sanding in-between coats. Make sure to wear a dust mask whenever you are sanding.

Give the seams another coat, this time feathering out to 6”. Again, lightly sand any rough edges.

11.

On the last coat, add a little water to the joint compound for a thinner consistency. Using a wide knife, feather the final coat out to 12”. Now just finish the job with a light sanding over every area with compound.
